By now, the majority of architectures have working relocation
support, so the few remaining architectures have become exceptions.
To make this more obvious, we make working relocation now the default
case, and flag the remaining cases with CONFIG_NEEDS_MANUAL_RELOC.

This patch removes the completely unused CONFIG_SERIAL_SOFTWARE_FIFO
feature from U-Boot. It has only been implemented for PPC4xx and was not
used at all. So let's remove it and make the code smaller and cleaner.

These architectures don't need relocation fixups, so reduce their
codesize a bit by defining CONFIG_RELOC_FIXUP_WORKS.
Also remove the reloc_off field from their global data structures
as it is no longer needed.
Note that the location of the standalone application jump table pointer
in the global data structure is affected by this change, breaking
execution of standalone applications compiled for previous versions of
U-Boot. We will therefore increment XF_VERSION in the next commit,
which also touches this area.

Add #ifdefs where necessary to not perform relocation fixups. This
allows boards/architectures which support relocation to trim a decent
chunk of code.
Note that this patch doesn't add #ifdefs to architecture-specific code
which does not support relocation.

So far the console API uses the following naming convention:
======Extract======
typedef struct device_t;
int device_register (device_t * dev);
int devices_init (void);
int device_deregister(char *devname);
struct list_head* device_get_list(void);
device_t* device_get_by_name(char* name);
device_t* device_clone(device_t *dev);
=======
which is too generic and confusing.
Instead of using device_XX and device_t we change this
into stdio_XX and stdio_dev
This will also allow to add later a generic device mechanism in order
to have support for multiple devices and driver instances.

Serial driver via the EmbeddedICE macrocell's DCC channel using
co-processor 14.
It does include a timeout to ensure that the system does not
totally freeze when there is nothing connected to read.

The Blackfin JTAG has the ability to pass data via a back-channel without
halting the processor. Utilize that channel to emulate a console.

This patch fixes a problem spotted on Glacier/Canyonlands (and most
likely lots of other board ports), that no serial output was seen
after console initialization in console_init_r(). This is because the
last added console device was used instead of the first added.
This patch fixes this problem by using list_add_tail() instead of
list_add() to register a device. This way the first added console
is used again.

This is expected by the callers, but this fact was hidden well within
the old list implementation.

* Add support for multiple serial interfaces
(for example to allow modem dial-in / dial-out)
- fix spelling errors
- set GD_FLG_DEVINIT flag only after device function pointers
are valid
- Allow CFG_ALT_MEMTEST on systems where address zero isn't
writeable
- enable 3.rd UART (ST-UART) on PXA(XScale) CPUs
